The present invention relates to a sleeve () for a disk brake fitted with a caliper slidably mounted in a carrier by means of pins fixed rigidly to the caliper, said sleeve () being designed to receive one of said pins in a bore of the carrier. According to the invention, such a sleeve is characterized in that it has ribs () on a surface designed to come into contact with the carrier so that said ribs () may be deformed in order to increase said contact surface when the sleeve () is compressed by an activation of the brake.

A mounting system for a brake pad in the housings of a disk brake yoke in which the brake pad comprises at its ends two mounting ears (), each ear being mounted in a housing of a disk brake yoke. The mounting system comprises for each pad ear, a spring () of linear or lamella shape, intended to bear, on the one hand, below a lower face () of the ear and, on the other hand, on the lower face of the housing of the yoke so as to separate the lower face () of the ear from the lower face of the housing.

Disc brake with a floating calliper and controlled brake piston, a movement conversion cartridge () comprising a rear part which is supported against the base of the receptacle in the calliper and a control shaft () which passes through the base. The cartridge () is retained in place by a cage () which is locked resiliently on the wall of the receptacle. The piston () comprises longitudinal ribs () which are placed in longitudinal grooves provided in the receptacle, with interposition of an anti-deformation device () interposed between the branches () of the piston () and the grooves of the receptacle of the calliper, and comprising a ring () which supports lugs () distributed according to the branches () and having cylindrical tongues which are curved according to the form of the cross section of the branches, and thus ensure the locking in rotation of the conversion piston (), whilst permitting its movement of translation.

A disc brake comprising a floating stirrup and a brake piston controlled via a motion conversion cartridge () comprising a rear part pressed against the bottom of the stirrup and a control shaft passing through the bottom. The front part of the cartridge is pressed against the brake piston. It comprises a piston () provided with a plate () cooperating with the plate () of the control shaft () with the interposition of balls cooperating with tracks in the form of ramps for transforming the relative rotational motion of the plate () relative to the other () into a translational motion of the piston (). The cartridge () is held in place in its housing () by a cage () attached elastically to the wall of the housing. The plate of the piston () comprises longitudinal grooves () receiving the branches () of a lock () which is elsewhere blocked in rotation in the housing of the stirrup while leaving the conversion piston () free in translation.

A disc brake comprising a floating stirrup and a brake piston controlled via a motion conversion cartridge () comprising a rear part pressed against the bottom () of the housing () in the stirrup () and a control shaft () passing through the bottom. The front part () of the cartridge is pressed against the brake piston. It comprises a piston () provided with a plate cooperating with the plate of the control shaft () with the interposition of balls cooperating with tracks in the form of ramps to transform the relative rotational motion of one plate relative to the other into a translational motion of the piston (). The cartridge () is held in place in its housing () by a cage () elastically attached to the wall () of the housing (). The piston () comprises longitudinal ribs () that fit in longitudinal grooves () produced in the wall of the housing () and thus ensuring the blocking of the rotation of the conversion piston () while allowing its translational motion.
